Indeed:

news <- function(package=NULL, lib.loc=NULL) {
    if (is.null(package)) {
        newsfile <- file.path(R.home(), "NEWS")
        title <- paste("NEWS for R-",
                       paste(R.version[c("major", "minor")], collapse="."))
    } else {
        newsfile <- file.path(system.file(package=package, lib.loc=lib.loc),
                              "NEWS")
        title <- paste("NEWS for", package)
    }
    file.show(newsfile, title=title)
}

[One might want to add the pager argument as in file.show.]

Yes, I do recall the thread that Greg started.  This is sort of trying to
get it going again...  Could we just settle on a standard name and be done
with it?  Since base R uses NEWS, why not just use that for all packages,
and use NEWS.platform as Duncan suggested (in the top-level directory,
rather than platform-specific directories)?
